-Central vision is when our eyes focus straight ahead, allowing us to drive, read, and see details sharply.
-Central vision only covers about three degrees of our visual field, but it allows us to make very important judgments like estimating distance and understanding details in the path ahead.
Our sharpest, clearest vision is called central conic and is only about 3 to 5 degrees. This is our most focused vision where we can identify details and color
Eruptions at shield volcanoes are only explosive if water somehow gets into the vent , otherwise they are characterized by low-explosivity fountaining that forms cinder cones and spatter cones at the vent, however, 90% of the volcano is lava rather than pyroclastic material.
